This book was released on 2017 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summer chum salmon (Oncorhynchus keta) in the Yukon River support robust commercial and subsistence fisheries; however, fishery managers have had incomplete information about their run timing, spawning distribution, stock composition, and abundance. To address this, a radiotelemetry study was implemented on summer chum salmon in 2014 and 2015. A total of 1,232 (2014) and 1,199 (2015) summer chum salmon were fitted with radio transmitters. Radiotagged summer chum salmon were mapped, travel rates were estimated, and proportions of tagged fish recovered within different tributaries were determined. Basic mark-recapture assumptions were tested and abundance above the tagging site was estimated. Summer chum salmon were found to be widely distributed within the Yukon River drainage. Although a few tagged fish were observed in most locations, roughly 50% of tagged fish were observed in the Anvik, Koyukuk, and Bonasila rivers each year. Summer chum salmon destined for upper river spawning areas traveled faster than those to lower river areas. Summer chum salmon tended to recover quickly after being tagged, and traveled relatively fast within the mainstem Yukon River, but slowed down after entering their spawning tributaries. The 2014 mark-recapture abundance estimate was about 2,100,000 fish, which corresponded with summer chum salmon passage at the mainstem Yukon River sonar near Pilot Station. The 2015 mark-recapture abundance estimate was also about 2,100,000 fish, which was larger than the summer chum salmon passage at the sonar near Pilot Station. Results from this study help to evaluate sonar passage estimates and provide fishery managers with more detailed information about distribution and migratory patterns of individual summer chum salmon stocks within the Yukon River drainagewide population.

This book was released on 2019 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of research conducted in 2014 on the local traditional knowledge of Chinook and chum salmon freshwater spawning and migration patterns in four Yukon River drainage communities. Researchers worked with respondents in Anvik, Huslia, Allakaket, and Fort Yukon to map environmental changes that may have affected salmon migration and spawning. Respondents interviewed for this study shared their lifetime experiences traveling, hunting, and fishing on the land and waters around their communities and shared their personal observations of change and changes they had heard of from others in their community or in neighboring communities. The study communities were chosen because of their proximity to an existing or an historical enumeration project. Proximity to enumeration projects gave researchers the opportunity to compare local observations of fluctuating salmon presence with existing data sets. Although this study intended to document possible changes to Chinook salmon spawning and migration, an abundance of environmental and ecological changes were also recorded. Over time, and especially in recent years, respondents have observed a variety of ecological changes. Some of these changes have impeded respondents' ability to participate in subsistence harvesting activities. Although more research is needed to explore each of these observations and their possible effects on Chinook salmon, it is clear that the environment that respondents are living in is rapidly changing and affecting all aspects of the natural world that they rely upon.

This book was released on 2020 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological data were collected from Chinook Oncorhynchus tshawytscha and summer chum O. keta salmon along the United States portion of the Yukon River drainage in 2018. Age, sex, and length data were obtained from 4,774 Chinook and 5,907 summer chum salmon from commercial and subsistence harvests, test fisheries, and escapement projects. Samples were collected from salmon caught using gillnets, dip nets, fish wheels, beach seines, weir traps, and from hand-picked carcasses. Sex and length were recorded for nearly all salmon sampled. Ages were successfully estimated for 89% of the Chinook salmon and 93% of the summer chum salmon. This report provides a summary of the age, sex, and length data collected in 2018 for Chinook and summer chum salmon and is a single source document for historical summaries of long-term projects that collect age, sex, and length data from the Yukon Area. This report also provides a brief description of the Arctic-Yukon-Kuskokwim Database Management System (AYKDBMS) which is a publicly accessible online data archiving system that acts as an interface to query and download historical age, sex, and length data.

Available in PDF, EPUB and Kindle. Book excerpt: Both the Alaska Department of Fish and Game (ADF&G) and the Canadian Department of Fisheries and Oceans (DFO) actively manage Chinook salmon Oncorhynchus tshawytscha and fall chum salmon O. keta fisheries in the Yukon River. Alaska is obligated to manage Canadian-origin Yukon River Chinook and fall chum salmon stocks according to precautionary, abundance-based harvest-sharing principles set by the Yukon River Salmon Agreement (Yukon River Panel 2004). This negotiated agreement represents an international commitment to the restoration, conservation, and management of Yukon River salmon, and is based on escapement management . Of importance to salmon management on the Yukon River is the ability to accurately assess the numbers of Chinook and fall chum salmon migrating through the U.S./Canada border. This project employs split-beam and imaging sonar equipment on the Yukon River to generate inseason passage estimates of Chinook and fall chum salmon migrating across the U.S./Canada border. Additionally, drift gillnetting is conducted daily to monitor species composition, and to collect biological data used in characterizing Chinook and fall chum salmon runs. The project is located approximately 30 km downstream from the U.S./Canada Border (Figures 1 and 2) and is scheduled to operate continuously from approximately July 1 through October 10 annually. This project has been fully operational since 2006 (Dunbar and Crane 2007).
